Question 31:A motorcyclist starts from rest and reaches a speed of 6 m...
Calculating acceleration of a motorcyclist
To calculate the acceleration of the motorcyclist, we can use the formula:
\[ v = u + at \]
Where:
- \( v = \) final velocity (6 m/s)
- \( u = \) initial velocity (0 m/s, since the motorcyclist starts from rest)
- \( a = \) acceleration
- \( t = \) time taken (3 s)
Substitute the values into the formula
\[ 6 = 0 + a \times 3 \]
Solving for acceleration (\( a \)), we get:
\[ a = \frac{6}{3} = 2 \, m/s^2 \]
Therefore, the acceleration of the motorcyclist is \( 2 \, m/s^2 \).
This means that the motorcyclist's speed increases by 2 m/s every second.
